Kitsune are capable of realizing and projecting illusions upon others. The villainous nogitsune of Season 3 is the only known kitsune to have exhibited this power. He was able to perform this talent to near-perfect precision.
In Riddled, the nogitsune trapped his host Stiles Stilinski in an illusion within his own subconscious, while the teenager is still asleep. Stiles sees himself in the basement of Eichen House and his left leg is caught in a steel-jawed trap. The void kitsune is able to alter the reality of the illusion while psychologically torturing Stiles. Suddenly the trap is on Stiles' right leg before switching back to his left.
In De-Void, he traps Lydia Martin and Scott McCall in illusions of their past: Lydia was taken back to the night of the school formal (Formality), and Scott was enagaged in a passionate encounter with Allison Argent during the time of Currents. Lydia was snapped out of the illusion by receiving Peter Hale's voice on the banshee frequency, and Scott broke himself free of the manifestation by remembering he and Allison weren't together at the time.
Suddenly, they're present in a reality consisting of a Japanese garden, where it's snowing. The Nogitsune, as his original host incarnation, communicates with them while mystically representing his real-time counterpart, Void Stiles. Scott and Kira are convinced they are fighting off the Oni. Stiles is finally able to deduce the reality is an illusion upon seeing reflections of school property on Kira's katana. Though they feel the pain and exhibit wounds from the Oni's blades, they eventually overpower the Nogitsune, which breaks the illusion.
Upon the reality's dissolution, Scott's Pack eventually appear at where they left off, the school's entrance heading into the building.
